The present invention provides leakage plugging devices and methods for sealing a leakage at a remote site in a pipe, the device including a porous carrier plug of a deformable material including pores and at least one sealant composition disposed in the pores, wherein the porous carrier plug is adapted to transport the at least one sealant composition from a first site to a remote site and to plug the leakage at the remote site.

A container (300) adapted to store a quantity of metal powder (101, 301), the container (300) comprising a container body having an opening and a sensing device (111, 121) for sensing the temperature of the powder (101, 301) and/or the humidity level inside the container (300), wherein a first reading received from the sensing device (111, 121) is compared to a second reading received from a second sensing device configured to sense the temperature and/or humidity level of an environment outside of the container, and based on the first reading and the second reading, a user is provided within an indication about whether the container can be opened.

The invention provides a cable drive device (10) including a linear drive member (12), and a cable drum (14) attached to a support bracket (30, 32) adapted to be affixed to a surface. The cable drum (14) has an axle (26) supported by the support bracket (30, 32) to allow rotation of the cable drum (14). The cable drum (14) has a cable (42) affixed at either end of said linear drive member (12) and tautly wrapped around the cable drum (14). The cable drum (14) is located between the ends of the linear drive member (12) to, in use, allow the linear drive member (12) to be guided through the bracket (30, 32) to move the linear drive member (12) longitudinally when the axle (26) is rotated.

High-pressure cryogenic fluid conduits that deliver high-pressure cryogenic fluids from a first point to a second point. This high-pressure fluid conduit has a safety feature that is activated when the high-pressure cryogenic fluid conduit fails due to exposure to a predetermined force. The safety feature is activated by the fracture of an annular ring that is positioned at either end of the high-pressure fluid conduit and is calibrated to fracture when exposed to the predetermined force. Fracture of the annular ring closes valves at each end of the high-pressure fluid conduit, thereby stopping the flow of high-pressure fluid from the high-pressure fluid source as well as the escape of high-pressure fluid from the high-pressure fluid container.

A magnetic connection system with at least three components for connecting host and target systems. A first magnetic connector is attached to the host system, a second magnetic connector is attached to the target system; a third magnetic connector or puck is positioned between the first connector and the second connector. The first, second, and third connectors fit together with their magnets aligned, and the magnetic attraction is stronger between the puck and the target system connector than the puck and the host system connector. The system can transfer fuel, data, or electricity. In one example, the system transfers fuel from a fuel supply vessel to a target vessel with minimal human effort to attach the fuel connector components. The puck can have a conduit for fuel, data, or electricity that is centrally aligned with a receiving conduit in the target system connector.

A coupling including female and male couplers configured to be connected together. The female coupler includes a valve body and a detent carrier surrounding the valve body and having a plurality of circumferentially spaced openings extending through a wall of the detent carrier for receiving detents to connect the female coupler to the male coupler. When the female and male couplers are connected together, the detent carrier is axially movable relative to the valve body by externally applied loads acting on the male and female couplers to cause the male and female couplers to separate. A pressure-balancing chamber is provided to prevent premature separation of the couplers. Once separated, the detent carrier axially moves back and the female and male couplers may be reconnected.

An inflator cap comprising: an outer cover; an anti-corrosion lining formed in or inside the outer cover; and a magnetic member formed on, in or inside the outer cover, whereby the magnetic member of the inflator cap, once unscrewed from the inflator, will be magnetically attractable on a ferromagnetic object to prevent its loss; or whereby the anti-corrosion lining will preclude a direct contact between the outer cover of the inflator cap and a valve stem of the inflator to prevent from sticking of the oxide of the outer cover once oxidized on the valve stem of the inflator, thereby smoothly unscrewing the cap from the inflator.

Apparatus are provided for an access system for a passage defined in a component. The passage is surrounded by a flange, and the access system comprises a plug adapted to be coupled to the flange of the component to seal the passage. The plug includes a sidewall and an overhang coupled to the sidewall. The overhang is configured to substantially surround at least a portion of the flange and the plug is movable between a first, unsealed position and a second, sealed position upon the application of a force.

A weak link arrangement (1) designed for location on an umbilical (6, 7) extending on the seabed between respective structures potentially subjected to environmental hazards, like being snapped by an iceberg, which umbilical includes communicating fluid pipes and electric cables, is described. The weak link arrangement (1) includes a seabed frame (2) supporting an umbilical having a weak link multiconnecting structure (3) (UTA) installed in line, which weak link multiconnecting structure (3) (UTA) ensures continuous communication through the fluid pipes and electric cables until emergency disconnection takes place. Such disconnection is initiated by accidental pull in the umbilical, which pull activates disconnecting means and cable severing means.
